30 Claims.

My invention relates to devices for the dispensing or withdrawing of articles, one by one, from a suitable receptacle or magazine which may at intervals be charged or supplied with a large number of such articles.

In accordance with my invention in its preferred form a supply of articles to be dispensed, for example, paper napkins, are placed in superposed relation upon a magazine follower or other feeding device and a movable member is brought into engagement with the uppermost article, pressing upon and moving along it, whereby one end of the article is caused to separate itself from the article beneath it to a sufiicient extent to permit another movable member to engage such end and move it into a position where it may be readily grasped by the user and withdrawn from the machine.

In the preferred form of the invention, the feeding device is a movable follower which exerts spring pressure upon a supply of articles carried thereby during at least a part of the dispensing operation and the invention contemplates the provision of means for relieving the uppermost article of such pressure at the time when it is to be withdrawn so that its withdrawal will be facilitated and the possibility of its causing any displacement of other articles is avoided.

One form or species of dispensing device embodying the invention is disclosed and claimed in my application Serial No. 331,074, filed January 8, 1929. Another species is disclosed and claimed in the present application which is, in part, a continuation of said application. It is applicants intention to claim the invention generically in the present application.

This application is also a continuation in part of my application Serial No. 355,065 filed April 15, 1929.

Reference is hereby made to the accompanying drawings, of which Figure 1 is a side elevation of a dispensing device constructed in accordance with my invention, the enclosing casing being removed;

Fig. l is a perspective view of the follower;

Fig. 8 is a plan view on a reduced scale illustrating the manner in which a napkin may be folded in order to be dispensed by the device and Fig. 9 is an enlarged detail view illustrating the action of the dispensing mechanism upon a folded napkin.

Referring to Figs. 1, 2 and 6, the device shown comprises a base 1, and a casing or body 2, preferably of metal, within which the working parts are housed. A door 3, preferably also of metal, is hinged to the casing and is provided with locking means 3 for securing same in closed position. Within the casing 2 and secured thereto and to the base 1 is a metal supporting frame. This frame comprises metal sheets 4 which form the side walls of the magazine within which the follower travels. The plates 4 are bent to form vertical channels or guides 5. The plates 4 are provided along their rear edges with integral flanges 6 and are secured together by a vertical metal plate 7 and corner angle strips 8, metal screws 11 passing through said strips, plate and flanges, as shown in Fig. 3.

The forward edges of the side plates 4 are secured together in a manner similar to the rear edges, with the exception that the vertical plate 7 and the corner angle strips 8 which correspond to the plate 7 and strips 8 extend only a short distance in a vertical direction, as shown in Fig. 1, so as to permit loading of the follower.

There is a pair of side plates 9 which are secured at their ends by screws 10 to the respective angle strips 8 and 8'. These plates support the dispensing mechanism.

The rear wall of the magazine is a vertical sheet 13 having integral flanges 14 which are secured to the walls 4 by screws 15. This wall has also a top flange 16.

The front wall of the magazine is formed in part by a vertical plate 1'7 which extends only a short distance below the top of the magazine as shown in Figs. 4 and 5. The space below this plate is normally closed by the panel 18 of the door 3, but when the door is opened, as shown in Fig. 5, the magazine is open throughout substantially its entire height and width to permit the easy loading of the follower with bundles of napkins.

The top wall of the magazine is a horizontal plate 19 having integral flanges 20 secured to the side plates 9 by screws 21.

The follower is shown in detail in Fig. 7 and comprises a sheet metal plate 22 bent into the form of an inverted U. The vertical walls 23 of the follower are provided with pairs of upper and lower guide rolls 24. These rolls may be conveniently supported by cutting and bending the metal of said walls to form integral ears or lugs 25 which support the horizontal pins 26 upon which the rollers 24 are journaled. Each roller extends into the opening in the wall 23 which is formed by the bending of said tongues. A single tongue instead of a pair of tongues may be used for supporting the roller, if desired.

One of the side walls 23 of the follower is provided with a toothed detent 2'7 which is rigid therewith and will be referred to later. Each side wall 23 has a stud 28 rigid therewith.

In assembling the device the follower is placed within the magazine with the outer edges of the rollers 24 occupying the channels 5. The studs 28 and the base of the detent 27 pass respectively through the vertical grooves 29 of the magazine walls 4, so as to permit vertical movement of the follower. The detent base and the stud which is on the opposite wall of the follower are fitted to said groove so as to aid in guiding the follower, said stud having an enlargement or roller 28 for this purpose.

The follower is normally urged in an upward direction by means of coil springs 30 and flexible tension members 31. The latter may be cords of any suitable material, one extremity of the tension member is secured to a stud 28 of the follower and extends thence over a sheave or pulley 32 rotatably mounted on the wall 4, thence around a pulley 33 rotatable in the floating frame 34, thence over a pulley 35 rotatably mounted on the wall 4, thence to the frame 34. One end of each of the coil springs 30 is attached to a frame 34 and the other end to 2. lug 36 rigid with a wall 4. By means of this arrangement a longitudinal contraction of the springs of one inch causes a three inch movement of the follower.

Any desired ratio of spring and follower movement may be obtained by varying the number of fixed and floating pulleys. In practice the arrangement shown for producing a 3 to 1 movement causes a substantial balancing of spring tension and follower weight. When the follower is in its lowest position and fully loaded with articles to be dispensed its weight is a maximum. At this time the spring 30 is at its greatest elongation and is exerting maximum tension on the cor-d 31. Such tension is sufficient to elevate the follower so as to cause the uppermost article to be pressed against the top plate 19 of the magazine with a moderate pressure.

As the articles are removed through the dispensing outlet, the follower is caused to rise. Its weight decreases at a uniform rate and the tension of the springs decreases at substantially the same rate, the effect of which is to cause the uppermost article to be pressed against the plate 19 with substantially uniform pressure, irrespective of the number of articles which are carried by the follower.

The means for separating one end or extremity of the uppermost article from those beneath it upon the follower and for thereupon moving such end so as to increase its separation and enable it eeaoeo to be readily grasped by the user is broadly new, and while adapted to operate upon articles of various kinds, has been very successfully applied to the dispensing of paper napkins folded in a particular manner, as will be described.

Referring to Fig. 8, a paper napkin a is preferably folded in opposite directions along the lines b and 0, thus producing a zig zag formation. It is then folded along the line (1. Various other types of fold may be used, as long as the final fold is along a line substantially equidistant from the ends of the napkins, and preferably at right angles to the longest dimension of the resultant article.

The napkins as thus folded are superposed to form a pile or bundle and loaded into the magazine in such manner that the line of fold of each napkin is at the left, Figs. 4 and 5.

The dispensing mechanism, shown in detail in Figs. 1 to 5, comprises a pair of levers 41 which are pivoted by screws 42 to opposite side plates 9 of the frame. These levers are united by a cross bar 44 integral therewith and having angle plates 45 to which is secured suitable hand operating means, as for example an arm 46 which passes through a slot 47 in the cover 12 and is provided with a button 48. Each of the levers 41 is provided with two arms 49 and 55, as shown. The arm 49 is substantially horizontal and is provided at its extremity with a pin 50 which engages a slot 51 formed in a plate 52. This plate is pivotally mounted on the side plate 9 by means of a screw 53. There are two of the plates 52, one mounted on each of the side plates 9 of the frame and such plates are united by a rod 67, one end of which is secured to each of said plates.

Upon the rod 67 is a sheet metal guard 38 which is held against turning thereon by engagement of an ear 39 with an aperture 37in one of the plates 52, see Figs. 3 and 4. In its normal position the guard 38 substantially closes the opening '76 in the cover plate 12, see Fig. 4.

Each of the plates 52 is provided with a pin which engages a slot 61 formed in a plate 62. The plate 62 is pivotally mounted on side plate 9 by a screw 63 upon which it turns. plates 62 are united by a rod 54. The cross section of this rod is preferably such as to form a sharp edge 54 (Fig. 9) for engaging the surface of the article to be dispensed.

The arm 55 of one of the levers 41 extends in a downward direction from the pivots 42 and at its lower end is provided with a pin 56 which engages a slot 57 in a lever arm 58. The arm 58 is pivoted at 59 to the plate 64 which is secured by screws 55 to side plate 9.

The function of the lever arm 58 is the actuation of the follower 22 through the following elements. A link 65 is pivoted at one end to arm 58 by a pin 66, the opposite end of said link being pivotally connected to a vertical bar 67 by a pin 68. The bar 67 extends practically the full height of the magazine frame and is provided with upper and lower slots 69 which cooperate with fixed pins 70 carried by plates '70 secured to the side wall plate 4.

One edge of the bar 67 is formed with ratchet teeth 71 in such position that as the bar is moved laterally said teeth will engage similar teeth on detent 27 carried by the follower 22.

The levers 41 are normally held in the position shown in Figures 1 and 4 by coil springs 74. One end of each spring is formed as a hook which passes through a hole in one of the arms 55 and the other end of said spring is secured in a similar manner to the side plate 9. the body of the The two spring being disposed in an opening 'formed therein. The tension of these springs is sufficient to move all parts from dotted to fullline positions, Fig. 4 thereby depressing the follower.

The cover 12 is removably mounted on the casing 2. This'cover is provided with a transverse slot 76 through which the dispensed articles may be withdrawn. In order that the same may be readily grasped, a trough-like depression 77 is formed in the cover, which depression is braced by a depending flange '78. The trough '77 forms an opening '76 in the cover" which is normally closed by the guard 38.

The operation of the device is as follows:

Assuming the magazine to be empty, the door 3 will be opened and the follower 22 depressed by hand, first releasing the same from the bar 67 by depressing the hand lever 46. Since themagazine is ordinarily of considerable height, a large number of articles to be dispensed, for example paper napkins, may be placed upon the follower, completely filling the magazine. The width of the door 3 is substantially the'same as or greater than the distance between the side walls 4, 4 of the magazine so that the napkins may be readily inserted. The door 3 is then closed and secured.

In order to obtain one of the napkins or other articles, the user depresses the lever 46 and causes the dispensing mechanism to move from the full line position of Fig.4 to that shown in dotted lines. Such movement by reason of the action of the lever arm 55 causes the arm 58 to move upward, thereby actuating the bar 67' and causing it to move upward and away from the detent 2'7 of the follower. The ratchet teeth 'llof the bar 67 are withdrawn from engagement with the teeth of the detent .2'7', and thereby free the follower and allow'the springs, 30 to cause the follower to move upward to the limiting position which is determined by the top napkins coming in contact with the plate 19, Figs. 4 and 5.

Simultaneously with the action which hasjust been described, the arms .49 of levers 41 cause the plates 52 to be moved from thefull line to dotted line position, Fig. 4, so that the uppermost napkins can readily move past the guard 38. The movement of the plate 52 by reason of. engagement of pin 60 with slot 61 causes the arms 62 and rod 54 to move from full to dotted line position Fig. 4. Since the follower 22 by reason of the resiliency of the coil springs 30' is holding the uppermost napkin in firmcontact with the said rod 54, the effect of the movement ofsaid rod is to cause the upper layer e of the napkin to exert a pull upon the lower layer I, whereby the end of the napkin at the line of fold is raisedand separated from those below it asshown in Figs. 5 and 9. This movement of the upper napkin is sufficient in extent to bring thefree end above the guard 38. The flange 16 of the plate 13'is to pre vent the napkins below the uppermost one from being elevated, or in case one or more of them should rise above said. flange they will be held against any lengthwise movement by the'end wall parts 13 which extend above the level of the flange 16, and will be brought below the said flange when the follower is depressed by the bar 67' as will be described.

With the parts in the position of Fig; 5, the user thereupon releases the button 48 and lever 46, and the coil springs 74 cause the parts to move from dotted to full line position of Fig. 4. These movements, being exactly the reverse of those which were caused bythe depression of lever 46, accomplished the following results, namely, bar 67' is caused to move laterally and downwardly until the teeth .71 engage the teeth of the detent.2'7 and the bar 67'. then moves straight. down-thereby depressing the follower a distance substantially equal to the vertical portion of the. slots 69. This. causes the uppermost napkin-to be relieved of pressure from below, so that it may be more readily withdrawn and so that when it is being withdrawn there will be no tendency for it to cause the napkin immediately beneath it to be displaced.

Simultaneously with the action just described, the rod 54 and guard 38 move from the full line to dotted line position Fig. 5. Theeifect of the 'movement, of the guard is to move the end of the uppermost napkin from full to dotted line position. It should be noted that the end of the napkin is now in the slot 76 of the cover and that by'reason of the trough'l'l it is very easy to grasp r such end of the napkin between the thumb and finger and withdraw the napkin from the device without displacing or disturbing in any way the articles which remain.

The device cannot be rendered inoperative by any jammingof articles therein due to operating the lever 46 again without removing the article which has been previously brought into position for withdrawal, for the reason that such second or repeated operation of the lever 46 will have no efiect upon the articles in the device, since the cross rod 54 engages only the uppermost article. It is impossible for the apparatus to cause the elevation of any article below the uppermost one sufliciently to enable it to be engaged by the guard 38. In'case the lever 46 is depressed without. removal of the article previously brought into position for withdrawal, the various parts will simply move idly from full line to the dotted line position of Fig. 4 and return without affecting any of the articles, and not until the uppermost article has been pulled out of the dispensing device by theuser does. it become possible to separate the next" article from those; beneath it in the magazine.
